In order to have a better understanding of the relation between vertical dimension and occlusal force,a meter was made by means of straingauge.Five Japanese men were investi- gated for occlusal force at different vertical dimensions.The measurements showed that the maximal occlusal force of the posterior teeth occured at 8 to 15mm or the vertical dimension, the maximal occlusal forec of the anterior teeth occured at 13 to 18mm.This indicated that the occlusal force was closely related to the state of jaw closing muscle.

OBJECTIVE:To provide suggestions for the setting-up of the current pharmacovigilance(PV)system.METHODS:The characteristics of the setup of the PV system in both US and France were analyzed and the problems encountered in current monitoring system of adverse drug effects were pointed out.RESULTS & CONCLUSION:Both American and French PV systems have their own advantages and we should learn from it and draw useful experiences from them.In constructing PV system,China should make improvement in organization,communication,financial resource and information technology etc.

Hospital construction is essentially disciplinary construction and personnel development. Improving the quality of department heads in an all round way and bringing into full play their potential and enthusiasm will be of great significance in promoting disciplinary and hospital construction and development. To give play to the role of department heads, it is imperative to enhance their quality, bring into full play their potential and enthusiasm, and appropriately handle relationships with them. Only by doing so can marked achievements be made in hospital construction and development.

Objective:To investigate the intervention effect of vitamin C for the treatment to diabetes patients with diabetes and gastric ulcer.Methods: 53 cases of patients with diabetes combined with gastric ulcer were selected as the research subjects, and were divided into a control group(23) and a intervention group(30). The patients in two groups were given the treatment of reducing blood sugar and anti-HP triple therapy. The intervention group was given additionally diet intervention via eating vitamin C. The blood sugar, blood lipid levels, gastric ulcer index and inflammatory markers of the two groups were reviewed six months later by helicobacter pylori type detector. And the statistical analysis was performed.Results: After treatment, the blood sugar, blood lipid levels, gastric ulcer index and inflammatory markers of the two groups were significantly improved (t=1.23,t=1.35,t=2.63,t=1.07,t=0.77,P<0.05), except for the HP cure rate (P>0.05). Other indexes of the intervention group are significantly better than the control group (t=1.45,t=1.67,t=2.33, t=1.55,P<0.05).Conclusion:Vitamin C play a very good role in the treatment and prevention for the blood sugar, the blood lipids, gastric function and inflammation of patients with diabetes and gastric ulcer, and helicobacter pylori type detector can simplify the detection of helicobacter pylori.

Objective To compare the efficiency of gauze packing , internal iliac artery ligation and tran-scatheter arterial embolization for controlling pelvic fracture hemorrhoea .Methods The clinical data of 23 consecu-tive patients with pelvic fracture hemorrhoea were retrospectively analyzed .There were 8 patients who had undergone gauze packing,6 patients undergone artery ligation ,9 patients undergone angioembolization .The ISS,the preoperative shock index ,the operation time of control the shock ,the postoperative blood transfusion ,the days in ICU after opera-tion and the complication were all recorded respectively .Results The operation time of control the shock ,the postop-erative blood transfusion and the days in ICU after operation of the packing group were ( 70.00 ±24.50 ) min, (1 050.00 ±207.02) mL and (10.12 ±1.64) d;the ligation group were (40.83 ±12.01) min,(1 800.00 ± 400.00)mL and (11.17 ±1.72)d;the angioembolization group were (91.67 ±22.64)min,(1 644.44 ±421.64) mL and (7.22 ±1.56)d.The difference between the three groups had statistical significance with the indexes above all(F=10.323,9.265,12.235,all P<0.05),and the ligation group had the shortest operation time to control the shock,the packing group had the least postoperative blood transfusion ,the angioembolization group had the shortest days in ICU after operation .There were 4 cases in the packing group suffering the infection ,the infection rates as high as 50%,one of them died on the 8d;there were one case in the ligation group died of MODS on the 11th day. Conclusion The gauze packing is a sample and effective hemostasis ,suitable for the patients with open fracture and the fist aid for pelvic fracture in the basic level hospitals;the internal iliac artery ligation can control the shock timely but the hemostatic efficacy is not better than the other two kinds of operation; the transcatheter arterial embolization has micro injury and effective hemostatic efficacy ,however ,the strong profession and the lage difficulty may delay the patients'condition .So the doctors should use the methods of hemostasis flexiblely and comprehensively .

Objective To investigate the chemical constituents in the leaves of Dracaena cochinchinensis.Methods The compounds were separated with column chromatography and their chemical structures were identified by physicochemical and spectral method,respectively.Results Thirteen compounds were isolated from the plant. They were identified as isorhamnerin(Ⅰ),quercetin(Ⅱ),25(R)-spirostane-5-en-3?-ol(Ⅲ),gracillin(Ⅳ),25(R)-spirostane-5-en-3?,14?-diol(Ⅴ),25(R)-spirostane-5-en-3?,14?-diol-3-O-?-D-glucopyranoside(Ⅵ),25(R)-spirostane-5-en-3?,14?-diol-3-O-?-L-rhamnopyranosy(1→4)-?-D-glucopyranoside(Ⅶ),25(R)-spirostane-14?-hydroxy-4-en-3-one(Ⅷ),7?-hydroxysistosterol-3-O-?-D-glucopyranoside(Ⅸ),?-stigmasterol(Ⅹ),stigmasterol-3-O-?-D-glucopyranoside(Ⅺ),daucosterol (Ⅹ Ⅱ),and methyl ?D-glucopyranoside(Ⅹ Ⅲ).Conclusion Spirostane-type steroids are the major constituents in the leaves of D.cochinchinensis.Compounds Ⅰ-Ⅲ,Ⅴ,Ⅵ,Ⅷ,and Ⅸ are isolated from this plant for the first time.

Superselective angiography and embolization is one of the important methods in the management of acute hemorrhage, providing mini-invasion and high efficacy, etc. The implication of angiography and embolization on bleeding were reviewed and the embolic agents as well as the interventional procedures were commented in this article.

OBJECTIVE To improve efficiency of hospital infection administration and take strict precautions against medical malpractice in Chinese level Ⅱ hospital of UN Peacekeeping Army in Lebanon.METHODS The current situations of its hospital infection administration were enumerated,compared and analyzed,and corresponding measures of administration were suggested.RESULTS Under the influence of characters of medical missions during peacekeeping,the hospital infection administration presented the problems that patients and disease spectra were diversified,the rate of hospital infection was influenced by peacekeeping mission,the positive rate of HIV was high,medical workers protection awareness was lagged behind,and the disposition of hospital was illegitimate;many measures should be taken to enhance the administration level.CONCLUSIONS In order to well develop the hospital infection administration in Chinese level Ⅱ hospital of UN Peacekeeping Army in Lebanon,we should reform and improve the system of hospital infection administration,and establish an effective and systematic prevention system of hospital infection.
